Molecular formula/chemical symbol :Mo

Description :
 

Molybdenum is a Block D, Group 6, Period 5 element. The number of electrons in each of Molybdenum‘s shells is 2, 8, 18, 13, 1 and its electronic configuration is [Kr] 4d⁵ 5s¹. In its elemental form molybdenum‘s CAS number is 7439-98-7. The molybdenum atom has a radius of 136.3.pm and it‘s Van der Waals radius is 200.pm. Molybdenum is toxic unless it is in small quantities. Molybdenum has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum is a catalyst in the oil refining. It has many other applications, including in catalysts, pigments, corrosion inhibitors and lubricants. It has a very high elastic modulus. Molybdenum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel.

USES :

It is used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel. Molybdenum is used in nuclear reactors and aerospace components. The primary commercial source of molybdenum is molybdenite (MoS₂), although it is also recovered as a byproduct of copper and tungsten mining.
